B&O subwoofer

Hi guys wonder if some can help me. I've  got a  B&O subwoofer in the boot of my Fiesta 2018 ST Line in the wheel well which I have removed temporarily. Off the harness in the car which connects to the subwoofer is a black plug with 4 wires in it. Does anyone know what these 4 wires are. Have tried to find a wiring diagram on line but no luck. Hope someone can help. Cheers

    The subwoofer is a dual coil, hence the 4 wires. I’ve put mine in a sub box, as I’ve changed to a spare wheel rather than use the repair kit.

    Cheers for the reply Jollyandy, do you what the 4 wires are off the plug from the car harness?????? I was thinking of fitting a slim line subwoofer in the boot probably a pioneer TS-WX130EA. I just need to know what the wires are, is one an ignition positive and the other a negative and the remaining 2 wires speaker wires. Just need to what's what. Colours of wires are Black, Yellow, Purple and Green. Cheers

    The four wires are in pairs for each voice coil in the subwoofer. There’s no power supply. You would need to remove the speaker from the housing to check which pair goes to which voice coil and find out the polarity.

    How do you disconnect the electric plug connector from the sub woofer?

    I can't seem to pull mine apart. 

    There's probably a simple method of doing it that I am overlooking. 

    Many thanks
